have a stock jdm b20 with a b16 head gsr cams lovefab manifold and a precision sc61 turbo and more bolt ons im tuning it on neptune rpt on 10 lbs of boost i wanted to know if it was better to run it on c16 race gas im wanting to run like high 11's

 

i don't suggest it

 

why?????

 

if your goal is 11 seconds...then running a stock b20 block isnt the best idea. your cylinder walls won't hold the power.

 

id get some arp rod bolts and keep it under 300whp and you should be fine. I wouldnt take it over 8k

 

If its a STOCK b20 bottom, I wouldnt take it anywhere past the redline of the b20. Just cause the head can hold 7500+ rpm's doesnt mean the b20 bottom can. One thing to remember is it was a truck engine and wasn't engineered for high rev's more for lowend torque.

 

yeah i thought so

 

get rod bolts then take it to 8k without problems

 

An SC61 is a bad turbo for a stock B20. It will not get close to its efficiency range because the B20 sleeves will let go after ~300whp. Get an LS block and try it...you might have better luck

agreed that's alot of turbo for a stock b20, if you do pistons and rods you'll be able to actally use the turbo, i'm using onne to get 500whp on pump and the b20 would not hold up to that

 

^^pistons and rods wont help on a stock B20...the sleeves are the weakpoint and would need to be addressed first. A piston/rod build on an LS would allow you to make upper 400s or low 500s on stock sleeves
